BigVelo Turns an iPhone Into a Cycling Cockpit

Field notes

The product assigns distinct roles to familiar cycling hardware: the iPhone supplies the dashboard and map, the Apple Watch supplies heart rate and wrist controls, and a Garmin Varia supplies rear-traffic data. The page describes radar states using green, amber, and red, with faster beeps as vehicles approach and a watch haptic when the alert escalates. Route input includes GPX files from Trailforks, RideWithGPS, Komoot, or Strava, alongside Apple cycling routes.
